Q & A for building and interfacing your rack gear with Ground Control Pro and GCX-based systems.

I have a GCX that is emitting strange cracking and popping noises after playing for about 2-5 minutes. Also, it has recently started making a loud hum or growl. Its running through a Mesa Mark V. The rack top down is a Furman power conditioner, then a TC Electronics G Major 2 and next is the GCX. The problem has just started and the current setup has been in place and working for 3 years without issue. We are using all George L's. Im in the process of checking each patch cable with a multi meter for a failure and planning cleaning all the jacks with contact cleaner which was never done before. Does it sound like my problem could be a ground loop?
Guitar into GCX>GMajor2>Amp Effects Loop. Is pretty much the order. The gcx and ground control pro handle amp switching etc.
